Python __repr__和__str__练习

'''
class Person(object):
    instance = None

    def __init__(self, name, age):
        self.name = name
        self.age = age

    def __repr__(self): # 可读性高，给程序员输出结果
        return f"reprname：{self.name}，age；{self.age}"

    def __str__(self): # 可读性高，给用户输出结果(优先级str>repr)
        return f"str姓名：{self.name}，年龄；{self.age}"

p1 = Person("huchangxi", 22)
p2 = Person("hulanxi", 6)
print(p1) # 姓名：huchangxi，年龄；22
print(p2) # 姓名：hulanxi，年龄；6
print(p1.name) # huchangxi

s = "hello"
print(repr(s)) #'hello'
print(s.__repr__())
